Thy Serpent started out as Sami Tenetz's one-man project back in 1993. During the first few years he recorded two demos, Frozen Memory in 1994 and Into Everlasting Fire in 1995.

Thy Serpent call their music "Anti-Christian Dark Metal", being they believe that black metal is supposed to be Satanic music, and because they are not Satanists and they don't want to call their music "black metal."
